I use a receiver hitch bike rack on the front of my TV. We have an Ultra-Lite and can't/ won't use a bumper rack. Bikes ride well in front. Can see them and they don't take up all that bed space in the Pick- Up.

I have seen bike racks made for the top of a closed PUP. I had been interested when we had a PUP but never looked further into it.

If you want to haul them on the roof of the pup, then look at Rackwharehouse.com under the Thule products, they have roof rails you can mount directly to the roof. I have used them in the past when I owned a pup and never had any issues, I could haul 3 kayaks or 5 bikes. The rails are difficult to find anywhere else and you won't find them in the fit guide programs. Then if you use the TK2 tracker feet, the rack will lock into the rails well. Sorry I don't have a picture close up of the rails by them self, but you can see from this picture what I was able to carry.

I've taken two trips so far with the Pro-Rac set up. The front tires of your bikes need to be removed, but this provides a solid attachment to the fork of the bike to the rack. The rack comes with straps, but I think I'll switch to ratchet straps to tighten the back of the bike down to keep the bikes from shifting.

I'm happy with the purchase - easy to install, adjust the height, no holes drilled in the roof.

I looked into the pass through hitch with bike carrier set up, but that adds quite a bit of tongue weight once you add the bike weight of 4-5 bikes.

I've seen those and wish we would have known about it when we had a pup. Its the best design out there for pop-ups IMO.

Out of curiosity, how much does the Pro-Rac with bikes add to the TW on your set-up?

I haven't formally calculated the TW yet, but I can't believe it is much. The carrier is an aluminum alloy vs. steel and it is mounted to the frame of the camper vs. handing on a hitch extension. The bikes are also resting on the roof, which helps with the weight distribution IMO.

I haven't seen a noticeable difference with two adult trek hybrid bikes and two kids bikes. I'll have to weigh the bikes and do some math.
